4 Climate-Vegetation equilibrium in the Indian sub-continent Sites for Palynological Study 1-3- Gujarat 4-7-South-western ghats South-east coast Central India
5 The Western Ghats, India Over 5,000 different plantsoccur in the Western Ghats. Around 1,700of these are found nowhere else in the world. Savanna Grassland Heterogenous Flora
6 High rainfall Water drains in the broad valleys Several lacustrine deposits Lakes surrounded by MontaneForest at different Altitude Lakes are the Excellent Archives of past Vegetation Vegetation tends to remain in equilibrium with the prevailing Climate Palynologicalstudy provides clue to Climate changes in the past.
7 CLIMATE-VEGETATION EQUILIBRIUM The Rainforest here occurs in the mist laden humid environment receiving 7-8 months of rainfall. Strengthened Summer Monsoon and Winter Monsoon The highlands (1500m altitude) obstructs the clouds resulting into heavy rainfall during SWM. The retreat of monsoon again showers rain in this region. The windward side towards the coast receives most of the rainfall and thereby, the occurrence of Rainforest Most of pollen from this region is transported to coastal /marine wetlands where they get preserved Therefore, the coastal sediments and Marine sediments serve as potential archive for monitoring climate through palynology.
8 Adverse Climate: Low Rainfall (During Cold & Arid Conditions- Glacial periods) Vegetation shrinks to Pockets in areas retaining soil moisture around water body, Crevices or shady areas where evaporation is minimum. Plant takes refuge in pockets
9 Commercial Exploitation of the land in western Ghats Loss in Plant Diversity Climate Change Enhanced by Anthropogenic activity
10 MONSOON SYSTEM OVER INDIA SWM-The Myanmar hills reflect the winds as a result the central part of India receives rainfall late in July. NWM-Winds passing over the land are drier. Winds passing over Bay of Bengal is moisture laden. South-east coast receives more NEM than SWM. West coast receives both the Monsoons. Highlands of Western ghats obstruct the Moisture laden Winds Coastline

22 Inferences from Palynological Record related to global Interglacial and Glacial Cycles HST & Rainforest in Eastern ghats HST & Rainforest in Western ghats
23 CONCLUSIONS Sea level highstandsrecorded both on the west coast (MIS 5a) and east coast (MIS 3a &3c) correlate well with the global records. During these periods Rainforest was dominant in western ghats& eastern ghats. LGM was most vulnerable period that reduced the vegetation to Savanna grassland in western ghatsas well as in most parts of the Indian sub-continent. Plants took Refuge in pockets during the glacial periods in favourableareas such as near water bodies, crevices or as riparian forest where soil moisture was sufficient for sustenance. Trees such as Cullenia, Dipterocarpus, Hopea, Shorea, Nypaetc shows its palynologicalevidence until middle Holocene in east coast as well. The advent of Holocene warmer climate and high rainfall rejuvenated the plant refugiain most parts of India which continued until around 3000 yrs. BP. A decline in moist forest is evident since ~3-2 ka in most parts of India. Several endemic rainforest taxa are at the verge of decline from south-western ghats. Rainforest pollen is recorded from Varkalaformation (Miocene) along the Kerala coast. The pollen morphology shows its affinity with present day pollen of rainforest present in Southwestern ghats. The Rainforest of south-western ghats shows endemism and is called as fossil flora. Our study of Pleistocene record points that the rainforest existed in continuity since Tertiary Period although the species extinction or migration cannot be ruled out. The monsoon circulation over southern India was similar since the Middle Miocene Climate Optimum and the flora in the south-western ghatsis a fossil ecosystem. During the late-holocene, shortening in the length of the monsoon season in response to decreasing solar insolationwas due to continuous southward migration of mean summer ITCZ (Fleitmann et al., 2007) from 7.8 ka to present. This could be responsible for the climatic changes that have occurred during this duration.
